For our latest mission, we staged a reenactment of the first Princess Leia / Darth Vader scene from Star Wars on a New York City subway car. The white walls and sliding doors on the train reminded us of the rebel ship from the movie, and we thought it would be fun to see how people would react to a surprise appearance by the iconic characters. We spread out the actors along the train line, staging it so they would enter the right car at the right time.

How could they possibly have any doubts that the other riders would love it? Link -via The Daily What
